Abstract

The invention belongs to the technical field of plastic processing, concretely relates to a PVC resin composition with a high pressure resistance and an excellent plasticity, and further discloses a PVC pipe prepared therefrom. The PVC resin composition with high pressure resistance and excellent plasticity adopts PVC resin, a PVC stabilizer, methyl methacrylate-styrene copolymer resin, toughnessmodified resin, a processing aid, calcium stearate, paraffin and PE wax as processing raw materials, and the coordination effects of all above components are used to effectively promote the plasticizing performance and plasticizing uniformity of the pipe and effectively improve the internal pressure resistance of the pipe. The methyl methacrylate-styrene copolymer resin and MBS resin can especially produce good synergistic effects, so the plasticization of the whole system is further promoted, and the internal pressure resistance and the processing plasticity of the entire PVC pipe are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of plastic processing, specifically relates to a PVC resin composition with high pressure resistance and excellent plasticity, and further discloses a PVC pipe prepared by the composition. Background technique [0002] Polyvinyl chloride (PVC, Polyvinyl chloride) is a polymer formed by the polymerization of vinyl chloride monomer in peroxide, azo compound and other initiators, or under the action of light and heat according to the mechanism of free radical polymerization. PVC used to be the world's largest general-purpose plastic. It is used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, fibers, etc. widely used. [0003] As we all know, due to its excellent chemical stability, excellent electrical insulation, good flexibility and colorability, PVC pipes ca...
